Using MYSQL/PHP/UD with PhaKt, but I'm definetly a newbie.I have a database field with the following term:
"lead-based paint"
I'm trying to run a query that will return a result.
The query is :
SELECT * FROM database WHERE term LIKE '%MMColParam%'
If I type in "lead" I get result. With "lead paint", no result.
I find if I type "lead%paint", I get results.
Is therea way to convert the spaces in a search from my form to "%" for wildcard?

Yes you should the FullText feature of MySQL which is exactly what you're looking for.
In short :
1. Create a fulltext index on the fields you're looking on : "ALTER TABLE tableName ADD fulltext(fieldName1,fieldName2,...)"
2. Your query changes in :
"SELECT * from tableNAme WHERE MATCH (fieldName1,fieldName2,..) AGAINST ('lead')"
Of course change tableName,fieldNameXX with your configuration.

Thanks for the help, this looks like what I need. One problem, I get the following error. Do I have a syntax error?
table:chrarchive
fieldname:headline
Error
SQL-query:
ALTER TABLE chrarchive ADD FULLTEXT headline
MySQL said: You have an error in your SQL syntax near 'headline' at line 1
table:chrarchive
fieldname:headline
Error
SQL-query:
ALTER TABLE chrarchive ADD FULLTEXT headline

Yes, when creating an index (any type) you need to enclose the fields you want to use into ( ). So your query is :
ALTER TABLE chrarchive ADD FULLTEXT<font color=red><b>(</b></font id=red>headline<font color=red><b></b></font id=red>
